There is a new apex predator in Logan County, West Virginia, wreaking havoc on the coyote population, the former top of the food chain. While local trappers are perplexed, AIMS has its own theory and suspects the legendary Devil Dog is to blame, sucking the blood and life from the coyotes. From eyewitness videos and pictures, the danger becomes even more apparent when they realize there is not one, but a pack of Devil Dogs on the loose and looking for blood. Something must stop this predatory pack before humans become their next target.
